Road and soil stabilisers

Chemical road stabiliser

A non-traditional (proprietary) stabilising agent for road base, sub-base and gravel layers. It is mixed into in-situ or imported material, then shaped and compacted, and works through road recyclers. Four products do this job; we help you choose by the material and the layer.

Type

Non-traditional (proprietary) stabilising agent

Specification

To your project specification and pavement design; the dose is set from laboratory tests on the job’s material

Application

Mixed in by recycler or grader, then shaped and compacted

Supplied as

Depends on the product: CRP88 in drums, flowbins or bulk; the bitumen stabiliser in bulk or 200 L drums; the stabilisation grade in bulk by tanker; RoadBinder’s pack confirmed on the quote

Technical support

Products for this job

• RoadBinder (MSBT), for marginal G9 to G5 material. Laboratory results: UCS above 1,200 kPa. Applied by in-situ recycling or central plant mixing.
• CRP88 polymer soil stabiliser, a co-polymer for unbound gravel roads, at 2.5–20 L/m³.
• Polymer-modified bitumen stabiliser, for in-situ material, in bulk or 200 L drums.
• SS60 stabilisation grade, for BSM-emulsion and emulsion-treated bases, in bulk by tanker.

Where it is used

• In-situ and imported base, sub-base and gravel layers.
• Gravel-to-sealed road upgrades, haul roads, platforms and base courses.
• Unbound gravel roads that take in water, struggle to carry traffic and need constant maintenance.

Also written as: road stabiliser, chemical stabiliser, non-traditional stabilising agent, proprietary stabiliser, base stabilisation, sub-base stabilisation, gravel road stabilisation, in-situ stabilisation.

To quote, send us

• The length × width × depth (m³), or the area.
• The material class or description, and laboratory results (grading, PI, CBR, UCS) or samples.
• In-situ mixing (recycler or grader) or plant mixing.
• The water source, the planned surfacing and the traffic.

Chemical soil stabiliser

A non-traditional (proprietary) stabiliser for in-situ soils. It improves weak, moisture-sensitive or marginal material (CBR, UCS and plasticity), so the material already on site can be reused.

Type

Non-traditional (proprietary) soil stabiliser

Specification

To your project specification; the dose is set from laboratory tests on the soil

Application

Mixed into the soil, then compacted

Supplied as

CRP88 in drums, flowbins or bulk; RoadBinder’s pack confirmed on the quote

Products for this job

• RoadBinder (MSBT), for marginal G9 to G5 soils. Laboratory results: UCS above 1,200 kPa.
• CRP88, a co-polymer soil stabiliser that also suppresses dust, at 2.5–20 L/m³.

Where it is used

• Marginal soils, G9 to G5.
• Roads, platforms and yards built on in-situ soil.
• Soil stabilisation that also has to hold the dust down.

Also written as: soil stabiliser, soil stabilisation, chemical soil stabiliser, polymer soil stabiliser, non-traditional soil treatment agent, in-situ soil stabilisation, platform stabilisation.

To quote, send us

• The area and depth (m³).
• The soil description and laboratory results, or samples.
• The mixing equipment and the water source.
• The planned use: road, platform or yard.

Bitumen emulsion stabilisation grade (60% anionic) for BSM and emulsion-treated bases

SS60 stabilisation grade: a 60% anionic slow-set emulsion mixed into base material, usually by recycler, to make bitumen-stabilised (BSM) or emulsion-treated base layers. It arrives in bulk by tanker, coupled to the recycler.

Grade

60% anionic slow-set emulsion (SS60 stabilisation grade)

Specification

SANS 4001-BT3, and your project specification

Mixing

Usually by recycler. Test the breaking rate with the job’s aggregate, filler and water first

Diluting

With clean water, adding the water to the emulsion

Supplied as

Bulk, by tanker coupled to the recycler

Technical support

Where it is used

• Stabilisation of base course material.
• In-situ recycling with emulsion (BSM-emulsion).
• Emulsion-treated base (ETB).
• Diluted, for slushing bitumen-stabilised layers.

Anionic emulsion does not suit acidic aggregates. For these, a cationic emulsion such as the cationic stable grade (CSS 60) is often considered instead.

Also written as: ETB, emulsion-treated base, BSM-emulsion, bitumen stabilised material, bituminous stabilising agent, SS60 stabilisation grade, emulsion stabilisation, slushing.

To quote, send us

• The length × width × depth (m³) of the layer.
• The parent rock or aggregate type, and the laboratory results.
• The emulsion percentage from the mix design, or ask us for help with it.
• The recycler details, the tankers needed per day and the water source.

Polymer-modified bitumen stabiliser for in-situ materials

A stabilising material of polymers, bitumen and surfactants that turns in-situ material into hydrophobic, durable and flexible base layers. It puts material that would otherwise be unusable to work, which cuts cost and environmental impact.

Type

Proprietary, non-traditional stabilising agent: polymers, bitumen and surfactants

Specification

To your project specification; the dose is set from a mix design

Application

Mixed into the in-situ material, then compacted

Supplied as

Bulk or 200 L drums

Technical support

Product selection, dosage and application guidance

Data sheet and safety data sheet on request

Where it is used

• Base layers built from in-situ material.
• Roads where the existing material would otherwise be unusable.

Also written as: polymer-modified bitumen stabiliser, bitumen stabilising material, polymer bitumen stabiliser, non-traditional stabilising agent, in-situ stabilisation, base stabilisation.
